How to enable function app's managed identity with service bus namespace?

Question

I want to connect my function app's system-assigned MI with the service bus namespace but when I go to the role assignment panel in Identity blade of resource, there's no option for service bus i.e.

I can surely apply permissions at the RG level but that'll violate the principle of least privilege.

If I go to the way that is assigning permissions via IAM- in the service bus like https://learn.microsoft.com/en-us/azure/role-based-access-control/role-assignments-portal?tabs=delegate-condition but before that if I check the managed identities in the Managed Identities tab in Azure portal, I cannot see any of the system-assigned managed identities there to assign them the permissions.

What's the way to go about it?
